David Gontier

David Gontier is a Lecturer in Mathematics at Paris-Dauphine University, affiliated with the CEREMADE research center. His research spans nonlinear analysis, spectral theory, and mathematical physics, with a focus on partial differential equations and quantum mechanics.

Research Interests: He investigates problems in

• Nonlinear analysis and calculus of variations
• Spectral theory, including applications to condensed matter physics
• Extremal combinatorics and geometric packing problems

Academic Contributions: David actively shares mathematical puzzles and educational content through his blog (thetatautau.fr), including problems on hat games, cake division, and Freudenthal-type logical puzzles. His work often bridges abstract mathematics with accessible problem-solving.

Additional Information: He has contributed to educational seminars, such as MATh.en.JEANS (2024), and maintains a collection of problems on topics ranging from irrational number distributions to torus-based watch puzzles.
